88-98 model year differences?

I'm a 73-87 guy, and i know a good amount about them. But I know nothing about 88-98. Anybody got a link to a site that has this run of trucks broken down by year? I'm just kinda bored, cruising the forums.

90 the interior door panels were changed and the bench seats had an arm rest added to them, the buckets went from low back to high back.

92 bucket changed again to a wider seat with an armrest.

93 the seats came with headrests, cup holders on dash, and also the ac controls had a rec button.

PASSLOCK uses the resistor in the key, but PASSLOCK II loactes the resistor in the ignition key cylinder. It only sends the correct signal when the correct key is entered into the cylinder.
